FACTURING COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENN SYLVANIA HINGE Application filed December 20, 1929. vSerial No. 415,466.

This invention relates broadly to hinges and more particularly kto hinges having means to assist in aligning or positioning the hinges with respect to a door or jamb. It relates still more particularly to hinges of the type having a portion adapted to engage theedge of a door or j amb whereby the relative position Vof the hinge and door or jamb is positively determined. v

Hinges have heretofore been.l provided which have had aligning or guiding portions adapted to lie along the edge of a'door or jamb to assist in proper` positioning of the hinges with respect thereto. The provision heretofore generally'made for this purpose has comprised a line or impression vin each of the hinge leaves, such line or impression being adapted to substantially coincide with a corner of the door to be` hung or the jamb to which the door is to be applied. c

In certain cases it has been'proposed to provide a hinge comprising leaves .having a portion of the metal thereof displaced relatively to other portions so as to provide an inclined portion terminating substantially in a straight line at its intersection with one of said leaf portions. This provision has been made for the purpose of providing a positive stop for abutting or lying againstthe edge of a door or jamb whereby the hinge might lbe applied in great measure by use of the sense of touch rather than having to rely almost entirely on the sense of sight. In such prior constructions the` portion of each'hinge leaf serving as an abutment is of extremely small area, in fact approximately little more than a line. What extremely small area has been provided has been generally inclined toward Vthe portion of the hingeleaf to be laid against the door or jamb so that only a very limited portion thereof serves as an abutment.

I provide a hinge comprising a leaf having an abutment portion of substantial area'extending substantially at right angles to the portion of the leaf adapted to lie against the surface of Va door or jamb, whereby to insure positive and accurate positioning of the hinge with respect to the door or jamb. y

I further provide a hinge comprising a pintle and leaves Aconnected therewith, each of such leaves having a substantially plane surface adapted to lie onra door or jamb, at leastone of such leaves having a substantially plane surface extending substantially at right angles to the first mentioned surface and adapted to abut the edge of the door or j amb to assist in positioning the hinge.

Other objects and advantages of the invention will become apparent as the following descriptionof a present preferred embodiment thereof proceeds.

In the accompanying drawing I have shown a present preferred embodiment of the invention, wherein Fig. l is an outside view of a hinge having 'its leaves spread out to lie in substantially the same plane on opposite sides of the pintle Fig. 2 is an inside view of the hinge shown in Fig. 1

Fig. 3 is a view looking at the hinge of Fig. 2 from its left-hand edge, viewing such figure;

Fig. 4 isa perspective view of a hinge leaf, being theI leaf shown at the right-hand side of Fig. 2; and

Fig. 5 is a cross-section taken on the line Ve-V of Fig. l.

Referring more particularly to the draw-y ing, reference numeral 2 designates a hinge pintle of usual form joining a pair of hinge leaves 3 vand 4, each. of which is provided with kpintle bearings 5, also of usual form. Each 'of the leaves 3 and 4 is providedwith a bearing portion 6y joining the pintle bearings thereof. Connected with the bearing p0rtion 6 of each leaf are lateralattaching exvensions 7 provided with holes 8 for the reception of screws. The lateral attaching eX- tensions are adapted to lie against the face of a door or jamb and to be connected therewith by screws passing through the holes 8.

The attaching extensions 7 are offset with respect to the bearing portions 6, as more clearly shown in Figs. 4 and 5. This offseting provides for the attaching extensions of both leaves lying in substantially the saine plane when the hinge is closed. This provision is made possible by staggering the attaching extensions so that those of one leaf will lie between those of the other leaf when the hinge is closed. Certain of the attaching extensions of a leaf may be joined at their outer extremities by a connecting por- Y tion 9 if desired. This adds strength and 'rigidity to the construction.

The attaching extensions of the respective leaves are so offset with respect to the bearing portions as to provide a subtanially plane surface 10 at the edgeofeachbearing portion and facing away from the pintle. As shown, each bearing portion has a plurality of such plane faces, all of which lie 'substantially in the same plane. They are substanti ally perpendicular tothe respective attaching extensions 7 so that substantially a right angle is formed between the plane of the attaching extensions and the plane of the faces or surfaces 10.- This right angle is adapted to receive a corner of a door or jamb to insure positive and'correct positioning of the hinge with respect thereto without the necessity of using great care to properly align Vthe hinge. In Fig.15 the hinge is shown as applied to a door 11 and a jamh 12- In forming the'hinge leaves as above described none of the hingek material is allowed to extend outwardly past the plane of the faces 10 except the attaching extensions 7, which are offset with respect to the bearing portions. In other words, the plane of the faces 10 is uninterrupted so that there is nothing to stand in the way of the direct application of such faces tothe edge of a door or jamb.v The oset of the attaching extensions is substantially completed between the pintle bearings of each leaf and the plane of the faces l0 thereof so that there is no inclined metal portion projecting outwardly beyond the plane of the faces 10 such as would interrupt such plane and prevent the direct application of the faces to the edge of a door or jamb.

The provision of hinge leaves having faces substantially corresponding `to the faces 10 above described is of great utility and advantage not onlyT in hinges whose leaves are adapted to lie substantially in the same plane when the hinge is closed, but also in hinges the leaves of which are adapted to lie aga-inst each other when the hinge yis closed. The

feature of providing a substantially square corner which is uninterrupted and adapted for directly receiving a corner of a door or ]a1nb to insure positive andV correct posisuch type are generally applied directly to the outside of the door and jamb, the necessity for providing mortices for the reception of the hinge leaves being obviated. When mortices are provided they may be such as to assist somewhat in the alignment of the hinge, but when no mortice is provided, as is normally the case in using hinges of the type referred to, the carpenter must rely entirely on the engagement between the hinge and the surface of the door to insure proper positioning and alignment thereof, and in such cases particularly the advantages of the present construction are most pronounced.

The leaves may be pressed out of suitable metal, the attaching lextensions 7 being offset Vfrom the bearing portions 6 in the press- 'ing operation. The faces 10 are provided substantially perpendicular to the faces of the attaching extensions adapted to lie against the doorfor janib yso as to provide the right angle for receiving a corner of the door or j amb. In the pressing operation the metal at the ljuncture of the each attaching extension 7 and the bearing portion 6 to which it is attached is moved into the desired plane of the attaching extension between the inside -of the bearing portion and the plane of the faces l0 so that such faces are exposed uninterruptedly in the direction facing away from the pintle bearings. The pintle bearingsare provided by a suitable bending operation.

By reason of the invention, the proper attachment of hinges todoors andv jambs is rendered much more facile than heretofore, because it is only necessary for the carpenter to lay the hinge against the corner of the door or jamb withV such corner in the angle be-v tween the faces 10 and the attaching extensions 7 whereby the hinge automatically positions itself in proper relationship both laterally and vertically with respect to the door or jamb. The provision makes it more diiicult to hang a door crooked than to hang it straight, as in order to hang the door crooked the carpenter would have to apply the hinge Vwith the corner of the door or jamb out of engagement with the corner provided in the hinge. Thus a great saving of time and labor is attained.

While I have shown and described a present preferred embodiment of the invention, it is to be distinctly understood that the same is not limited thereto, but may be otherwise variously embodied within the scope of the leaves, at least one of such leaves having a. shoulder between the pivotal connection of the leaves and the outer extremity of such leaf, such shoulder facing generally away from the pivotal connection of the leaves and being adapted to abut an edge of a door or jamb to assist in positioning the hinge, the material of the leaf being removed outwardly of the shoulder and the shoulder being discontinuous opposite the portion of the leaf projecting beyond the shoulder.

In testimony whereof I have hereunto set my hand.

WILLIAM J. WILSON.
